Seismic exploration process enabling the suppression of ghosts due to reflections at the water surface, and process for processing seismic data in order to suppress these ghosts

摘要

The invention relates to a process for marine seismic exploration at least two different depths by means of streamers, each including a set of hydrophones, the acquisition of data at the different depths being performed in a single exploration region, and in which the position of the streamers and the hydrophones when acquiring seismic data at a first depth is independent of the position of the streamers and hydrophones when acquiring seismic data at a second depth.
